Leverage disaster recovery with reliable support and cost-effective future-proof features

Zerto is straightforward to implement because it only requires the installation of an agent on the VMs designated for migration. A service, typically a VM, must also be deployed at the disaster recovery location. This entire process is simple and can be completed within three days. Zerto's near-synchronous replication occurs every minute, allowing for highly granular recovery points. This means that even if interruptions or malware disruptions occur within that minute, Zerto can restore to the last known good state, effectively recovering the entire setup to the latest backup. This capability ensures high data security and minimizes potential data loss. One of the main benefits of implementing Zerto is its data compression, which significantly reduces the load on our IPsec VPN. Zerto compresses data by 80 percent before transmitting it across the VPN, minimizing the data transferred between geographically dispersed locations. This compression and subsequent decompression at the destination alleviate the strain on the VPN, preventing overload and ensuring efficient data synchronization. Zerto simplifies malware protection by integrating it into its disaster recovery and synchronization features. This comprehensive approach eliminates the need for separate antivirus setups in virtual machines and applications. It streamlines our security measures and removes the need for additional software or solutions, resulting in an excellent return on investment. Zerto's single-click recovery solution offers exceptional recovery speed. Through the user interface, a single click allows for a complete restoration from the most recent backup within two to three minutes, enabling rapid recovery and minimal downtime. Zerto's Recovery Time Objective is excellent. In the past, if a virtual machine crashed, we would recover it from a snapshot, which could take one to two hours. With Zerto, the recovery process takes only five minutes, and users are typically unaware of any disruption. This allows us to restore everything quickly and efficiently. Zerto has significantly reduced our downtime. When malware affects our data, Zerto immediately notifies us and helps us protect other applications, even those not yet implemented with Zerto. By monitoring these applications, we can quickly identify and address any potential malware spread, minimizing downtime across our systems. Zerto significantly reduces downtime and associated costs during disruptions. Our services are unified, so in the event of a disruption without Zerto, even a half-day disruption would necessitate offline procedures. This would lead to increased manpower, service delays, and substantial financial losses due to interrupted admissions and other critical processes. By unifying service processes, Zerto minimizes the impact of outages. Zerto streamlines our disaster recovery testing across multiple locations by enabling efficient failover testing without disrupting live services. Traditionally, DR testing required downtime of critical systems, but Zerto's replication and failover capabilities allow us to test in parallel with live operations. This non-disruptive approach ensures continuous service availability while validating our DR plan, even in scenarios like malware attacks, by creating a separate testing environment that mirrors the live setup. This comprehensive testing provides confidence in our ability to handle real-world incidents effectively. This saves us over 60 percent of the time. Zerto streamlines system administration tasks by automating many processes, thereby reducing the workload for multiple administrators. This allows them to focus on other university services that require attention and effectively reallocate support resources from automated tasks to those requiring more dedicated management. Zerto is used exclusively for our critical services, providing up to a 70 percent improvement in our IT resilience.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"While the challenges posed by the difficulties were significant, they prompted the replacement of problematic components, resulting in the resolution of issues. Importantly, there were no substantial ongoing concerns. Regarding the overall performance, it has been consistently excellent."

"I am impressed with the tool's technical alliance with Veeam and Veritas."

"I find it easy to use, and the UI is really easy to navigate. We reduced our time with backups from days to less than half an hour for the same data service."

"The most valuable feature is how quickly it powers down the original source VMs and the speed at which it powers up the new VMs. The amount of time it takes to put up the operating system is valuable. The speed is what I like the best."

"Moving the VPGs from one location to another is a valuable feature. You just click on it and move it and it's done."

"The most valuable feature is real-time replication, where we have the ability to recover things in near real-time."

"Zerto has enabled the team to focus on engineering and spend less time developing APIs to work with custom solutions and security applications, positively impacting our IT resiliency strategy."

"Its ability to roll back if the VM or the server that you are recovering does not come up right is also valuable. You have the ability to roll back a few seconds or a few minutes. The rollback feature is great."

"Most of the time, this is at least a two person job. We used to have three people doing it. Previously, when we had a disaster recovery drill, the way it worked was 12 of us would show up in the office on a Friday night and work overnight from 12:00 AM on Friday night to 8:00 AM in the morning on Saturday. Then, three of us would be working for four hours out of those eight or nine hours just getting applications up and running in Arizona. Now, for the disaster recovery drill, I just stay onsite to help and assist anybody else as they need during that time frame and my work is done in about a 30-minute time frame. This is compared to the four or five hours it used to take for the three of us to do it."

"RPO time for the copied-off VMs appears to be quite short."

More Zerto pros

Cons

"Perhaps the most notable area for enhancement lies in the web interface for management. The current limitations in LDAP editing capabilities are not addressed in the UI, and I haven't observed any recent updates. It's possible that the new version of the DXI service incorporates improvements in the GUI, but I cannot confirm. While there is room for improvement in the current GUI, it remains a relatively minor issue. Overall, the system is comprehensive, covering aspects such as reports on latency and networking, leaving little room for additional enhancements in those areas."

"The product needs to improve performance while scaling out. It also needs to improve stability."

"When we are trying to upgrade any virtual machines, we have to stop the virtual machines that have been replicated in Zerto and then upgrade or update to the virtual machines onsite. Instead of having to do it manually, there should be some way of automating that particular function."

"I would suggest improving automatic updates. Their software requires updating level by level to keep it current. I was unaware that I was several versions behind, so I needed assistance to guide me to the current version."

"Some of the ability to automate selections and automate VPG creations could be better."

"The time between releases is too long. Zerto doesn't seem to really keep up with the products with which they need to be compatible. For instance, the 9.5 updates 3 took about 90 days to come out after the latest version of vCenter 7.0 update 3 was released."

"The replication layer can probably be improved."

"I don't like the evacuation process. The host evacuation process could be a little simpler too. It takes our maintenance a bit longer, when we are doing host maintenance, because we still need to evacuate the vRAs manually. I know they tried to make it more automatic, but it is not quite there yet."

"I always get some blowback about the cost. It does not seem too bad to me. We had to upgrade to a premium subscription to get some other features. Maybe a one-size-fits-all option would be better."

"The number-one area in which they need to improve their product is what I would call "automatic self-healing." This is related to running them at scale... We have 1,000 VRAs and if any one of their VRAs has a problem, goes offline, all of the customer protection groups and all of the customers that are tied to that VRA are not replicating at all. That means the RPO is slipping until somebody makes a manual effort to fix the issue. It has become a full-time job at my company for somebody to keep Zerto running all the time, everywhere, and to keep all the customers up and going."

Pricing and Cost Advice

"I do not oversee this aspect, as pricing is contingent on factors such as volume, technical specifications, and the desired features. Consequently, I lack information on the pricing details and structure."

"It was a little bit expensive. It took a long time for us to get DR for our workstations. It's one thing when you have 15 servers, but when we needed to bring on almost another 200 users, and each was the same price as the servers, it was too expensive. But Zerto worked with us and gave us a solution that was pretty decent in terms of price."

"The solution is very cost-effective and very easy to set-up but does not compromise on features."

"The cost is not dirt cheap but also is not terrible."

"The last time I looked at pricing, it was very good. It's much cheaper by far than VMware."

"While conducting our proof of concept, I compared prices with just one other vendor. At the time, the price for Zerto was more favorable."

"Its pricing is way better than Veeam."

"The solution is expensive, but it's worth the price."

"I think everything can be cheaper. Pricing limited our ability to use Zerto as much as we'd like, but that's not why we haven't adopted it as our primary backup solution."
